I own two Waspinators® (EM238) and I like them since they
are effective against wasps, but I still have one issue. Because
of the wind, they tend to get flat and they have to be reshaped
regularly. I came up with a simple solution. I fill the Waspinator®
with a large plastic bag, bottom first. Then I fill the plastic
bag with newspapers, tie it down twice and close the Waspinator®.
Last year, this set-up lasted all summer long. I thought you
might want to pass this tip on.
